Key takeaways
- 75% of CVs received in high-volume recruitment do not match role criteria: the first filter is the main bottleneck.
- With voice AI, the time before first contact drops from 3-7 days to under 24h, and 100% of ATS profiles are automatically completed.
- 330,000 calls made by Alex in 2025, 80%+ completion rate, 25 minutes saved per call: real production results, not projections.
The high-volume recruitment paradox
Too many candidates. Not enough good ones. Too little time to tell them apart.
This is the daily reality for recruiters in logistics, healthcare, hospitality, staffing, and retail. 77% of organisations practice high-volume recruitment, yet only 45% consider their strategy effective.
The core problem: 75% of CVs received for high-volume roles do not match the role criteria. Recruiters spend on average 40% of their working week on initial screening calls. And in the meantime, the best candidates are already hired elsewhere — they stay available for just ten days on the market.
Voice AI pre-qualification is not a gimmick. It is the structural answer to this paradox.
The bottleneck no one wants to name
The problem with high-volume recruitment is the first filter. Regardless of the volume of applications received, someone has to do the sorting. And that manual sorting is slow, costly, and a source of bias.
| Indicator | Value | Impact |
|---|---|---|
| Average time-to-hire | 44 days | Best candidates leave in 10 days |
| Candidate dropout rate | 66% without news within 2 weeks | Pipeline drains away |
| Mobile application abandonment | 60% | Field profiles lost |
| Cost of a vacant position | ~€500/day | Direct and indirect losses |
| Recruiter screening time | 40% of the week | Less time for value-added work |
This gap between application and first human contact is where good profiles disappear. Voice pre-qualification reduces this gap to a few hours, or even minutes. Estimate the financial impact of these delays on your business with our ROI calculator.
Before / After: what voice pre-qualification changes
| Indicator | Manual process | With voice AI (Alex) |
|---|---|---|
| Time before first contact | 3 to 7 days | < 24h (often < 1h) |
| ATS data completion rate | 60-70% | 100% |
| Recruiter time per candidate | 25 min screening + data entry | Report reading only |
| Interview completion rate | Variable | 80%+ |
| Selection bias | Present (human subjectivity) | Reduced (identical questions for all) |
| Volume processable per recruiter/day | ~15-20 candidates | Unlimited |
What voice captures that a CV does not
A CV says what the candidate has done. Voice says who they are and whether they are truly right for the role.
In a few minutes of voice interview, Alex collects what application forms never capture: actual availability (immediate, with notice, from what date?), scheduling constraints (shift work accepted? weekends? nights?), geographic mobility (accepted radius, vehicle?), authentic motivation (why this role, why now?).
This information is not in the CV. It is not in the application form. And it often makes the difference between a successful hire and a probation period departure.
AI-led interviews increase offers by +12%, hires by +18%, and 30-day retention by +17%.

Fairness as a business and regulatory argument
An often-underestimated benefit of voice pre-qualification is fairness. When every candidate is asked the same questions in the same order, the unconscious biases of human recruiters are mechanically reduced.
In the context of the AI Act, this is also a compliance argument: Omogen integrates bias detection through dedicated models and complete observability of every AI decision.
In high-volume recruitment, the first filter is the bottleneck. Voice AI transforms it into a competitive advantage without sacrificing quality or fairness.
